Essay

The correlation between the presence of conditions for dissociative attachment of electrons to electronegative gases in N2-O2 mixtures and the change of I-V characteristics and electrodynamic characteristics across four discharge modes was shown in the thesis. It was shown, that more efficient ozone synthesis is observed in modes where conditions for dissociative electron attachment to oxygen molecules are present. It was shown that the effect of electronegative impurities in N2-O2 mixtures on the I-V characteristic of the non-stationary current mode with positive polarity is determined by the dynamics of the pulsed component of the discharge current, the contribution of which decreases as the concentration of electronegative impurities in the N2-O2 mixture increases. It was demonstrated that the energy consumption of the constant component of the discharge current, which is determined by the ion drift, does not affect the dynamics of ozone synthesis under the mode of non-stationary current of positive polarity. Reducing the contribution of the constant component caused by pulse power supply increases the efficiency of ozone synthesis. The results of the conducted research create the physical basis for the development of the latest plasma chemical reactors, it was allowed to develop a plasma chemical system for reducing microbiological contamination of agricultural crops.
